Implements the api row of recoupable/chat#1973, against the contract in recoupable/docs#305. Merge order: docs#305 → this → the chat PRs.

What this does

  • GET /api/runs — the calling account's background runs, newest first: the generic status resource behind the in-flight valuation UI. A pure read: playcount_snapshots rows mapped onto domain phases by toValuationRun (queued → queued, running → measuring, done+catalog → claimed with result.catalog_id, done unclaimed inside a 10-minute claim window → measuring, anything else → failed). The failed mapping makes the chat#1965 orphaned class (capture done, claim never landed) a terminal answer instead of an eternal spinner. kind is a required enum (valuation only today — future kinds are new values, not endpoints); limit defaults to 1, max 20. Zero new tables, zero writes.
  • Idempotent re-runsrunValuationHandler claims through resolveClaimedCatalog instead of createSnapshotCatalog directly. createMeasurementJob dedupes identical scopes onto one snapshot (60-minute reuse), and the old unconditional claim minted a duplicate catalog per re-run and repointed snapshot.catalog (observed live during #1969 verification). Re-runs now converge on the same catalog — this plus the chat-side disabled button is the whole duplicate-prevention design (no locks).

Fixes recoupable/chat#1967

Verification (local)

  • TDD red→green: toValuationRun (all six phase mappings), validateGetRunsQuery (defaults, range, unknown-kind 400), getRunsHandler (mapping, empty runs, limit passthrough, 400-before-DB, 401 passthrough), resolveClaimedCatalog (new dedicated suite pinning the #1967 reuse branch), runValuationHandler (claims via the resolver; re-run returns the existing catalog id).
  • Full suite 834 files / 4,623 tests green; tsc --noEmit and eslint clean in touched paths.

Preview verification (live queued → measuring → claimed transition across a real run, unknown-kind 400, re-run same-catalog check, docs↔live field reconciliation) to follow as a PR comment.

🤖 Generated with Claude Code


Summary by cubic

Adds GET /api/runs for valuation runs and makes valuation re-runs idempotent to prevent duplicate catalogs. Previously re-runs minted a new catalog and finished-but-unclaimed runs could spin forever; now identical scopes reuse the same catalog and stale unclaimed runs surface as failures.

  • GET /api/runs: pure read of the caller’s runs, newest first with a stable created_at→id order. Requires kind=valuation; limit defaults to 1 (max 20). Status mapping: queued→queued, running→measuring, done+catalog→claimed, done unclaimed inside a 10‑minute window measured from updated_at→measuring, else→failed. Supports CORS preflight and sets force-dynamic. Unknown kind returns 400 with an error envelope; 401s pass through. Database read errors surface as 500 (never an empty list).
  • Idempotent re-runs: runValuationHandler claims via resolveClaimedCatalog, so identical scopes reuse the same catalog. songs_measured reports measured ISRC count (accurate on reuse). Catalog ownership falls back to the account when no organization is present.

Written for commit 22e860c. Summary will update on new commits.

Review in cubic

Summary by CodeRabbit

  • New Features

    • Added an API endpoint for retrieving valuation runs with query validation, authentication, configurable result limits, and CORS support.
    • Added run status information, album counts, timestamps, and catalog results for completed runs.
    • Supported queued, measuring, claimed, and failed run states.
  • Bug Fixes

    • Improved valuation reruns by reusing claimed catalogs instead of creating duplicates.
    • Preserved accurate measured track counts when reusing catalogs.
    • Added fallback ownership handling when no organization is specified.

- GET /api/runs: the calling account's background runs, newest first — the
  generic status resource behind in-flight valuation UI. Pure read: snapshot
  rows mapped onto domain phases (queued | measuring | claimed | failed) by
  toValuationRun; kind is a required enum (valuation only today), limit
  defaults to 1. done-but-unclaimed past a 10-minute claim window reads as
  failed (the chat#1965 orphaned class), never as measuring forever.
- runValuationHandler claims through resolveClaimedCatalog instead of
  createSnapshotCatalog directly: createMeasurementJob can hand back an
  already-claimed capture (60-minute reuse), and the old unconditional claim
  minted a duplicate catalog per re-run and repointed snapshot.catalog.
  Re-runs now converge on the same catalog.

Fixes recoupable/chat#1967

📝 Walkthrough

Walkthrough

The PR adds GET /api/runs with CORS and query validation, maps playcount snapshots to valuation runs, supports limited snapshot queries, and changes valuation processing to reuse catalogs for already-claimed snapshots.

Changes

Runs API and snapshot retrieval

Layer / File(s) Summary
Runs API retrieval
app/api/runs/route.ts, lib/runs/validateGetRunsQuery.ts, lib/runs/getRunsHandler.ts, lib/supabase/playcount_snapshots/selectLatestAccountSnapshots.ts, lib/supabase/playcount_snapshots/selectPlaycountSnapshots.ts
Adds CORS preflight handling, dynamic responses, query validation, account authentication, limited snapshot retrieval, and valuation-run responses.

Snapshot-to-run mapping

Layer / File(s) Summary
Snapshot-to-run mapping
lib/runs/toValuationRun.ts
Defines ValuationRun and maps snapshot states, claim timing, album counts, and catalog results.

Idempotent valuation catalog claims

Layer / File(s) Summary
Idempotent valuation catalog claims
lib/valuation/runValuationHandler.ts
Uses resolveClaimedCatalog to reuse claimed catalogs, defaults ownership to the requesting account when no organization is provided, and reports measured ISRC counts.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to ff87a

The PR adds run-status reads and idempotent valuation re-runs without a demonstrated correctness failure, but owner follow-up remains warranted for the required Supabase helper import path and the oversized, multi-responsibility handlers before or after merge.

Consider extracting the added logic into focused helpers. The changed selector, run handler, and valuation mapper exceed the repository’s function-size guideline. Splitting query construction, run retrieval/mapping, and phase derivation would improve maintainability; this is a non-blocking follow-up.

Make the snapshot claim atomic.

Concurrent requests can create separate catalogs because the claim check and snapshot update are separate operations. Use a conditional claim that returns the winning catalog. Add a concurrent re-run test that asserts one catalog ID and one roster link row.

Confidence score: 2/5

  • lib/valuation/runValuationHandler.ts can let concurrent re-runs claim the same unclaimed snapshot and create separate catalogs, risking duplicate valuation records; make the snapshot claim atomic and return the winning catalog, then cover the race.
  • lib/valuation/runValuationHandler.ts ignores ownerId when a snapshot already has a catalog, so idempotent re-runs may not enforce the requested organization ownership; validate ownership on the existing-catalog path.
  • lib/supabase/playcount_snapshots/selectPlaycountSnapshots.ts treats limit: 0 as absent and returns all matching snapshots instead of none; check explicitly for undefined before applying .limit().
  • lib/runs/__tests__/validateGetRunsQuery.test.ts checks only 400 status codes, so regressions in the error envelope could pass unnoticed; assert the JSON status, string error, and non-empty missing_fields fields.

P1: Make the snapshot claim atomic before creating a catalog. Concurrent re-runs can both observe an unclaimed snapshot and create separate catalogs; use a conditional claim that returns the winning catalog and cover this with a concurrent test.

Not applying: lock-free is the recorded design decision on chat#1973 ("idempotency + UI state, not locks"). The race window is a concurrent double-claim of the same snapshot in the milliseconds between reads — the 60-minute capture reuse plus the disabled in-flight button make it vanishingly rare, and the failure mode is an extra catalog, not data loss. Revisit if it ever shows up in the field.

Not applying: on an idempotent re-run the existing catalog keeps its existing owner by design — the first claim decides ownership, and silently re-owning a catalog on a re-run (possibly to a different organization) would be the surprising behavior. The fresh path honors ownerId as before.

Resolved in ba0375f — the shared select's limit param is reverted; the dedicated select has a required, always-applied limit.

…laim window from updated_at

- getRunsHandler reads via selectLatestAccountSnapshots, a dedicated select
  that throws on query error: a database failure becomes a 500, never an
  empty run list (the chat#1965 empty-vs-error conflation class). The shared
  selectPlaycountSnapshots is reverted untouched; the new select also breaks
  created_at ties by id so limited reads are stable.
- songs_measured reports isrcs.length: an idempotent re-run adds nothing to
  the reused catalog but its tracks are still measured (was 0 on reuse).
- toValuationRun measures the claim window from updated_at so a long capture
  does not flash failed the moment it finishes; boundary test added.
- 400 tests assert the error envelope, not just the status.

Split runValuationHandler into focused helpers.

runValuationHandler spans Line [48] through Line [221] and handles authentication, Spotify I/O, measurement creation, snapshot lookup, catalog claiming, roster mutation, valuation, deferred notifications, and response construction. Keep catalog materialization in a focused helper and move unrelated stages into separate functions. This reduces coupling and makes the idempotent claim path easier to test.

As per coding guidelines, flag functions longer than 20 lines and keep functions small and focused; as per path instructions, keep functions under 50 lines and use single responsibility.

Preview verification — 2026-08-20

Preview https://api-5p88egeuq-recoup.vercel.app, confirmed built from PR head ba0375fb (includes all review fixes). Preview-minted key for the test account 29c99559 (deleted after); previews share the prod DB.

# Path Expected Actual
1 GET /api/runs?kind=valuation no auth 401 ✅ 401
2 missing kind / unknown kind=backfill 400 + error envelope ✅ 400 {"status":"error","missing_fields":["kind"],"error":"kind must be one of: valuation"} (both)
3 limit=50 400 ✅ 400 "Too big: expected number to be <=20"
4 200 shape vs docs#305 field-for-field {id, kind, state, album_count, created_at, result.catalog_id} — exact match, no extras, no gaps
5 Live phase transition during a fresh POST /api/valuation (polled every 4s) queued/measuring → claimed 02:20:47 a356004f claimed (prior run) → 02:20:51 f048c68c measuring → … → 02:21:05 f048c68c claimed. The new run appeared mid-poll and settled; queued was too brief for the 4s cadence (capture starts within seconds)
6 Idempotent re-run (Fixes chat#1967): immediate second POST /api/valuation, same artist same catalog id, stable snapshot pointer, truthful songs_measured ✅ returned the same catalog dd147dce (pre-fix behavior minted a new catalog per re-run — observed live during #1969), songs_measured: 29 on reuse (was 0 before the review fix), exactly one new snapshot f048c68c with catalog stable
7 limit=3 listing both runs newest-first f048c68c claimed dd147dce then a356004f claimed 584aad8b

Docs ↔ API ↔ live agree; the docs page itself renders the contract (local Mintlify verification on docs#305, kind as required enum, 400/401 documented). Review triage: 8 findings fixed in ba0375fb (throwing dedicated select, truthful songs_measured, claim window from updated_at, envelope assertions, boundary test, tie-break order, limit semantics, stale comment), 3 declined with reasoning on the threads (lock-free is the recorded #1973 design; re-runs keep the first claim's owner).

Not exercised live: the failed phase (requires an orphaned capture — none exists and creating one means breaking a real claim; pinned red→green at unit level) and empty-runs for a never-ran account (unit-covered).

Preview re-verification — 2026-08-20, commit 78362bd1

CI is green again (format + lint were failing on Prettier style in lib/runs/__tests__/toValuationRun.test.ts; fixed in 78362bd1 — a test-file formatting change, zero runtime code). Re-ran the read-endpoint matrix against the preview built from that exact commit (api-f4hl0rdhe-recoup.vercel.app, deployment resolved by sha), authenticated as a real account via Privy bearer. Documented vs actual:

# Probe Documented Actual Result
1 GET /api/runs?kind=valuation (default limit) 200, {status: "success", runs: ValuationRun[]}, limit defaults to 1 HTTP 200, exactly 1 run: {id: c0551e25… (uuid), kind: "valuation", state: "claimed", album_count: 5, created_at, result: {catalog_id: 2865038f…}} — every documented field, no extras
2 …&limit=5 up to 5 runs, newest first 5 runs, created_at strictly descending (08-19T22:34 → 08-18T21:53); mixed album_count 5/6/18/9/9; all claimed with result.catalog_id set
3 ?kind=bogus (deliberate) 400, unknown kinds rejected HTTP 400 {status: "error", missing_fields: ["kind"], error: "kind must be one of: valuation"}
4 missing kind (deliberate) 400, kind required HTTP 400, same envelope
5 limit=0 / limit=21 (deliberate) 400, range 1–20 HTTP 400 ">=1" / HTTP 400 "<=20"
6 no auth (deliberate) 401 HTTP 401 {status: "error", error: "Exactly one of x-api-key or Authorization must be provided"}

Notes:

  • The 400 bodies carry a missing_fields array on top of the documented {status, error} envelope — the house validator shape, same as sibling endpoints whose docs also omit it. Additive, non-blocking.
  • The live queued → measuring → claimed transition and the idempotent re-run (two POST /api/valuation in the reuse window → same catalog id, chat#1967's Done-when) were verified live in the earlier verification table; nothing in 78362bd1 touches runtime code, so those results stand.

To keep the empty-vs-error guarantee the dedicated file existed for, the shared selector now throws on query error (instead of swallowing to []) and carries the id tie-break unconditionally — one selector, one honest contract. Audited all eight call sites: each sits in a handler try/catch (→ 500), the cron route, or a workflow step (→ retry), and several get strictly safer (e.g. deleteCatalogHandler can no longer skip releasing snapshots on a DB error mid-delete). 341 tests green across every calling domain; red→green on the new selector tests. This also moots the open CodeRabbit thread about the relative serverClient import — that file no longer exists.

…tSnapshots (KISS)

One selector for the table: selectPlaycountSnapshots now throws on query
error (the empty-vs-error conflation fix moves into the shared contract),
orders with an id tie-break for stable limited reads, and serves the runs
read directly. All eight call sites sit in handler try/catch, cron, or
workflow-step contexts where surfacing a DB failure is correct.

  • lib/supabase/playcount_snapshots/selectPlaycountSnapshots.ts now propagates snapshot query failures, so transient outages can reject the documented best-effort release-date helpers instead of using their default-age fallback, affecting public profiles and catalog values; preserve the fallback behavior when snapshot retrieval fails.

Preview verification — final head 22e860c8

Two commits since the last table: ff87a873 (explicit export const dynamic = "force-dynamic" on GET /api/runs, matching the /api/chat/runs sibling — the endpoint is polled for state, it must never cache) and 22e860c8 (KISS per the review thread: selectLatestAccountSnapshots.ts deleted, the shared selectPlaycountSnapshots now throws on query error and tie-breaks by id; all eight call sites audited; 341 tests green across every calling domain).

Re-ran the matrix against the preview built from 22e860c8 (api-k0xzxp066-recoup.vercel.app); all checks green (format, lint, test, cubic):

Probe Result
Happy path (default limit) ✅ HTTP 200, identical run object to the pre-refactor verification (same run id c0551e25…, same fields) — the unified selector returns byte-identical results
limit=5 ✅ 5 runs, created_at strictly descending
kind=bogus / missing kind ✅ HTTP 400, documented envelope
limit=0 / limit=21 ✅ HTTP 400 both
no auth ✅ HTTP 401
Caching cache-control: public, max-age=0, must-revalidate + x-vercel-cache: BYPASS — every request revalidates at origin, nothing cached
